Title: 방송용 카메라의 블랭킹 제어회로
Filed: 1998-05-27
Abstract: 본 발명은 방송용 카메라의 블랭킹(Blanking) 제어회로에 관한 것으로서, 특히 영상신호가 입력되는 증폭기(OP)의 반전입력단자(-)와 출력단자 사이에 궤환저항(Rf)과 블랭킹 구간에서만 ON되는 JFET(J1)를 병렬 연결하고, 영상신호가 입력되는 증폭기(OP)의 비반전입력단자(+)와 그라운드 사이에는 통상시 ON 상태를 유지하여 RON 저항을 나타내는 JFET(J2)를 설치하여 블랭킹 구간의 잡음 등을 거의 확실하게 제거할 수 있고, 블랭킹 레벨을 기준레벨인 V BL 과 거의 일치시켜 블랭킹 구간에 동기신호가 실릴 경우 주사선의 동기에 발생할 수 있는 오류를 현격하게 줄일 수 있음은 물론 기존의 블랭킹 회로보다 그 구조가 훨씬 간단하고 개념적으로 이해할 수 있어 방송용 카메라를 개발하게 되었을 경우에 그 비용을 대폭 절감할 수 있도록 한 것이다.
